Gigi Hadid and Bradley Cooper showed off their first public display of affection in London on Thursday. In photos exclusively obtained by The Post, the 28-year-old supermodel and 49-year-old “Maestro” actor held hands as they walked through the streets of the city. The sighting came hours after the pair, who have been rumored to be dating since October 2023, were photographed catching a flight out of New York City together on Tuesday.Hadid wore the same white T-shirt and black leather jacket in London as she wore to the NYC airport, but traded her baggy jeans in for a loose-fitting pair of slacks.
